ROLLING WINDOW-BLIND.

SPECIFICATION forming part of Letters Patent No. 531,944,dated January 1, 1895.

lApplication tiled April 4, 1894. Serial No. 506,245. (No model.)

To @ZZ whom it may concern.'

Be it known that I, CHARLES HUMMEL, of the city of St. Louis and State of Missouri, have invented certain new and useful Iruprovements in Rolling Window-Blinds, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

The object of this invention is to provide improved means for excluding light from a room, and permitting the entrance of air thereto.

lily invention consists in the novel construetion, combination and arrangement of parts hereinafter specified and claimed.

Referringlto the drawings: Figure 1 is an outside elevation of a window, illustrating the application of my device. Fig. 2 is a sectional elevation on the line 2-2 ot' Fig. 1. Fig. 3 is a horizontal section on the line 3 3 of Fig. l. Fig. 4 is an enlarged horizontal section on the line Llet of Fig. 2. Fig. 5 isa vertical section on the line 5-5 of Fig. 6. Fig. 6 is a face View of Fig. 5. Fig. 7 is a vertical section of the preferred rollable curtain. Fig. 8 is an inside view of the connecting straps therefor.

In the construction of the device as shown, the numeral 10 designates a Window-sill, and 11, 11 the jambe of the frame, and 12 the the header thereof. Formed in the header 2 is a slot 13, and located transversely of, and above the said header, in a cavity 11i formed therefor, is ashaft, or drum, 15. Fixed to, and mounted upon, the shaft 15 is a curtain, or blind, 16, which said blind depends through the slot 13 to a point in contact with the sill 10 outside of the window.

The blind 1G comprises a plurality of slats 17, fixed at their opposite ends and centers to suitable metal straps 1S, or strap sections 27 the said slats having transverse oblique apertures 19 therein, which said apertures have their outer ends in a lower plane than the inner ends thereof. The slats 17 are each provided With shoulders 20, adapted to overlap the exterior faceof the slat next below. the same, and the corners of the adjacent edges of said slats on the interior thereof, are cut away.

Fixed to the lower end of the blind 16 is a bar 21, which said bar is provided with transverse slots 22, adapted for manual engage ment, whereby the said blind may be drawn downwardly.

Mounted upon the opposite end portions of the drum l5 are drums 22, 22 of greater diameter than the drum 15, and fixed to, and wound upon, the said drums 22a, are cables, or cords, 23, 23,which said cords depend through pockets 24, 2d provided therefor in the window frame to points ot attachment to screwhooks 25, 25, located in the lower portion ol' said pockets.

A door 26 is formed in the Window frame, adjacent to each of the screw-hooks 25, and providing access to the pockets 2l, 24.

In the preferred roller curtain, the'details of which are shown in Figs. 7 and 8, the slats 17 are individually mounted upon strap-sections 27, by means ot'screws 28, the said screws being seated in the said strap-sections and passed through slots 2C) in the next adjacent strap-section, the end portions ot' the strapsections overlapping each other, as shown in Figs. 7 aud S, thus providing a sliding connection between the said sections and permitting the vertical movement of the slats independently ot', and relative to, each other. A plurality ot the sections 27 are joined to form a strap, the length of the completed eurtain, or blind, and three of these straps are employed passed through vertical apertures iu the end portions,and centers,ot the slats 17.

This device is mounted upon a drum, and manipulated in the saine manner, as is described in connection with the device shown in Fig. 1.

The operation ot this device is as follows: When it is desired to elevate the blind, the same being in the position shown in Figs. 1 and 2, the door 26 is opened, the cord 23 adjacent thereto, released trom the screw-hook 25 and pulled downwardly, thus unwinding the said cord from the drum 22, rotating said drum, rotating the drum 15, and winding the blind upon said drum 15. The cord is then reattached to the screw-hook 25, and retains `the curtain, or blind, in an elevated position,

so long as desired.

Then it is desired to employ the blind 16 as a shade, the cord 23 is released from the screw-hook 25, and the blind drawn down- IOO wardly bythe application of manual force to the bar 21.

It is obvious that in the practical use of this device, the light may be entirely excluded, and the air as Well, by approximating the slats, or any number of light and air admitting apertures may be provided by separating said slats, longitudinally of the straps.

It Will be observed that the shoulders 20, on the slats, overlapping the contiguous edge of a slat next below the same, Will prevent the introduction of the direct rays of the sun therethrough.

In a device ofthe class described, the combination of a curtain comprising a plurality of Vslats .provided With a plurality of vertical In testimonywhereof Iafx my signature in z5 presence of two Witnesses.
